The fixed-dose combination of daclatasvir, asunaprevir and beclabuvir is an oral antiviral medication that was developed for the treatment of chronic hepatitis C virus (HCV) infection in adults. Daclatasvir is an NS5A inhibitor, asunaprevir is an NS3 protease inhibitor, and beclabuvir is an NS5B polymerase inhibitor. The combination was developed for interferon-free treatment of HCV but has not received FDA approval and its global development was discontinued.
Pharmacokinetics
Pharmacokinetic parameters based on healthy adult volunteers after administration of the fixed-dose combination tablet under fasting conditions.
